His ambition, since taking up the sport aged 11, has been to compete at a Paralympic Games.
Three times a month he trains at the Great Britain training centre in Stoke Mandeville, while the remainder of the time he trains at home – and has been known to set up targets in his conservatory, then take aim from his living room.
Tim shoots right handed, due to having his left hand amputated, and was determined to make a success of shooting after hearing people say he would be not be able to.
The 20-year-old finished 12th and 22th in the 2013 European Championships before moving onto the world stage in 2014, where he finished eighth and 14th, respectively, in the R5 and R4 10m air rifle categories.
His best result came in 2015, though, when he won the Stoke Mandeville World Cup, in the R5 10m air rifle, prone, event.
